Testing analog component video SDTV (CE) CRTs
This section describes how to test CRT televisions with standard definition component
video inputs. The examples show the 882C. However there are notes that describe the
differences related to the 882D.
To set up the generator to test an analog component video SDTV display:
1. Connect a VGA-to-RCA cable between the VGA connector on the generator and the
YPbPr inputs on the display under test.
2. Identify the component television formats to test. These formats are listed after the
composite television formats in the generator’s default Source list. Begin with the first
format in the range of standard definition component television formats (480i).
3. Determine additional formats to test based on the resolution of the television display.
The television specification sheet will provide information on what resolutions to test. It
is necessary to test only those resolutions with the supported scanning type (typically,
interlaced for a standard definition television).
4. Determine the images to test. For analog CRTs you typically want to select images to
test for geometry, focusing, photometry, resolution, cross talk, centering, EMI, and
regulation characteristics. For more details on what images test these specific display
attributes, see “
To activate the VGA interface on the output port:
1. Press the
Interface key. A listing of signal interfaces appears on the generator’s display
as shown below on the 882C).
2. Choose the
VGA item by pressing the adjacent soft key. The interface is activated and
the port outputs the currently selected image and format. An asterisk is shown beside
the selected interface.
Alternatively, to activate the interface through the command line interface, enter the
following commands:
9
// Selects the VGA interface
// Applies the interface setting to the generator
If you are using the 882D generator use the DVI-A interface selection.
To verify the test set-up:
1. Press the
Source key to access the list of formats.
